My invention relates to improvements `ininumquantityof S02 derivcd'vfromthe burning` of sulphur in air.

Wherean excess of SO2 is used, an acid reaction follows, Which it is 4,necessary yto correct kby lan alkaline reagenmund its `isespecially desirable to eifectrthe ,bleaching with as small a 4quantity of .sulphur `fumes as possible. t 4

oneof `which is shownun part l, and thus further intimate association of the liquid with the products of combustion rising upward is secured. A third deflector L2 may be provided to screen the outlet b of the pipek B, and this outlet is placed high enough from the bottom of the sulphur box to prevent the liquid accumulating in the bottom of said box from finding its way into the pipe B and flowing back to the furnace A.

lhe paddle wheels M and M may be rotated in any convenient way, as b r the belt O and pulley P driving the sha t N; on which the shaft or pulley Q is mounted, which carries the cross-belt R, driving the pulley S on the shaft N, or any other convenient way of driving these paddle wheels may be adopted, as desired.

By having the products of combustion enter the sulphur box in the cool condition, the reaction will not be so vigorous as if the gases were applied hot, and consequently these gases will flow up through the sulphur box and will have an opportunity to be intimately mixed with the downward descending liquid, and thus a more uniform sulphitation will be secured, and the gases escaping from the chimney G will have very little, if any, traces of sulphur remaining therein, but will be mostly inert nitrogen with small quantities of other gases associated therewith, which will not affect the sulphitation of the liquid.

By the herein described arrangement, a very small quantity of sulphur fumes may be distributed uniformly through a large mass of liquid, and the slow reaction that results will enable the sulphitation to be uniform and sufficiently complete for practical purposes, using only a VveryV small quantity of sulphur.

The draft for the gases flowing throu h the apparatus may be controlled by t e valve h and steam jet H.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:
